MACHINE FOR CLEANING AND RECONDITIONING PIPE.

Application Med December 6, 1924. Serial No. 754,449.

pipe being cleaned, said pipe forming a,

track on which the machine runs while in operation, and the machine isso designed that it may be readily mounted on the pipe and dismountedtherefrom.

A further feature of the invention resides in the provision of novelmeanswhere'by the pipe may be thoroughly coated with a uniform coat ofpaint, simultaneously with the cleansing operation. I

With the above and other objects in view this invention has particularrelation to cer tain novel features of construction, operation andarrangement of parts, an example of whichis given in this specificationand illustrated in the accompanying drawings, wherein Figure 1 shows aside elevation of the machine.

Figure 2 shows a plan view thereof.

Figure 3 shows a fragmentary rear elevation thereof, mounted on the pipewhich is shown in section, taken on the line 3-3 of Figure 2.

Figure 4 shows a transverse sectional view taken on the line 4-4 ofFigure 1.

Figure 5 shows a fragmentary sectional view taken on the line 5-5 ofFigure 4.

v Figure 6 shows a transverse sectional view taken on the line 66 ofFigure 1, and

Figure 7 shows a transverse sectional view taken on the line 7-7 ofFigure 1.

Referring now more particularly to the drawings, wherein like numeralsof reference designate similar parts in each of the figures, the numeral1 designates the pipe being cleaned and reconditioned. At intervalsburied pipe lines must be raised and cleaned and repainted. The machineis illustrated as accomplishing this work.

The frame of the machine includes suitable side members 2, 2. These sidemembers are preferably channel irons, and they are connected by suitablearches, as 3. A motor 4 is mounted on the rear end of the frame andassociated with it is the fuel tank 5. The machine is mounted on thefront and rear carrier wheels 6, 6 and 7, 7 These carrier wheels arefixed on the respective axles 8 and 9 which run in suitable end bearingsdepending from the frame. These respective carrier wheels are spacedapart and run on the pipe 1. The front wheels 6 are serrated, havingratchet-like teeth which engage with the pipe to propel the machmealong, and the inner corners of the rear wheels 7 bite into the pipe tohold the machine in vertical position thereon.

The motor shaft 10 has a spur gear 11, fixed thereon, which is in meshwith and drives the spur gear 12, fixed on the line shaft 13, and thisline shaft carries a fixed screw gear 14 which is in mesh with anddrives a worm gear 15, fixed on the front axle 8, The machine is thuspropelled along the pipe 1. Y

Swung from the front end of the frame there is the bearing ring 16 whichis fastened to the respective side members 2 by means of the arms 17,17. This ring is formed with spaced bearings 18 through which thebearing rods 19 extend, and on the respective ends, of these rods, whichextend beyond said .bearings, the respective rollers 20, are mounted,and these rollers may be provided with any desirable type of antifriction bearings. Within the ring 16 there is a sleeve 21 formed withthe rear and front peripheral annular flanges 22 and 23 which abutagainst the adjacent rollers 20 and confine said rollers in the racewaysthus provided. Both the bearing ring 16 and the sleeve 21 are formed oftwo lengthwise sections, as shown in Figure '1. The abutting parts ofthe ring sections are formed with adjacent outturned ears 24,25 to theformer of which the lock bolts 26 are pivot-ed, which are adapted to fitthrough the slots 27, of the latter, and are locked therein by means oflock nuts28 threaded onto said bolts, and

which may be unscrewed to release said bolts to take the ring sectionsapart. The sections of the sleeve 21 have abutting ears 29 with setbolts 30 securing them, and the sleeve sections, together.

The flange 22, of the sleeve 21, is former] with a gear face 31, whichis in mesh with. and driven by the intermediate spur gear 32. This spurgear is mounted between the front arches 3, 3 and in turn is in meshwith, and driven by, a driving gear 33, which is fixed on the driveshaft 34. This drive shaft is aligned with the motor shaft 10 and isarranged to be clutched therewith, and deelutched therefrom, through theclutch 35. which is manipiilated through the clutch lever 36.

Projectin forwardly from the front flange 23, of the sleeve 21, andfixed to said flange, are the supporting rods 37, preferably four innumber, whose forward ends are anchored to the sectional annular anchor38. A rotatable framework is thus pro vided which revolves about thepipe 1 and carries the pipe cleaners presently to be. described.Pivotally mounted on the forward end of each rod are the spaced levers39, 39. Between the forward ends of these levers the cylindrical,rotatable toothed cutters are mounted. Pivotally mounted on each rod 37,behind the levers 39 is a similar lever 41 whose forward end carries abrush 42. The rear end of each lever 39 and 41 carries a hingedextension 43, having the flat end bearing 44 and interposed betweenthese hearings, and the ends of the levers underneath are the coilpressure springs 45 which operate to hold the cutters 40 and brushes 42yieldingly against the pipe to be cleaned. The hinged end of eachextension 43 has an upstanding arm 46 and adjusting screws 47 arethreaded through these arms and work against the corresponding leversunderneath. The tension of the springs 45, and the pressure of the pipecleaning devices, against the pipe may be varied through these adjustingscrews 47, and the pipe cleaning devices also thus accommodated to pipesof different sizes.

Operatively connected to the motor 4 there is an air compressor 48 whichmaintains air pressure in an air pressure tank 49, through the pressureline 50. The numeral 51 designates a paint receptacle, and the numeral52 designates an annular nozzle around the pipe 1 behind the pipecleaners. This nozzle has an inside row of perforations, or nozzleopenings all the way around the pipe 1, to be painted.

Leading from the compression tank 49, and the paint receptacle 51,respectively are the lines 53 and 54, which unite and enter the nozzle52. These lines are controlled by the usual valves 55 and 56.

As the machine advances along the pipe the cutters 40 loosen up theincrustations on the pipe, and partially remove the same, and thefollowing brushes 42 sweep oif any re maining foreign matter clinging tothe pipe. The pipe is thus completely cleaned, and prepared to receivethe paint which is sprayed onto the same, in a uniform coat from thenozzle 52.

What I claim is 1. A machine for cleaning the outer surface of pipeincluding a carriage, a motor thereon, a cleaner connected to thecarriage, motor operated means for rotating the cleaner about the pipeto clean the same, wheels supporting the carriage onthe pipe, some ofsaid wheels having teeth which engage with said pipe.

2. A machine for cleaning the outer surface of pipe including acarriage, a motor thereon, a cleaner connected to the carriage, motoroperated means for rotating the cleaner about the pipe to clean thesame, wheels supporting the carriage on the pipe, some of said wheelshaving teeth which engage with said pipe, and means establishing adriving relation between the motor and Said toothed carrier wheels.

3. A machine for cleaning the outer surface of pipe including acarriage, a motor thereon, a cleaner connected to the-carriage, motoroperated means for rotating the cleaner about the pipe to clean thesame, wheels supporting the carriage on the pipe, some of said wheelshaving teeth which engage with said pipe, and other of said wheelshaving edges which bite the pipe to secure the carriage against rotationon the pipe.

4. A machine for cleaning the outer surface of pipe including acarriage, a motor thereon, a cleaner connected to the carriage, motoroperated means for rotating the cleaner about the pipe to clean thesame, wheels supporting the carriage on the pipe, some of said wheelshaving teeth which engage with said pipe, and other of said wheelshaving edges which bite thepipe to secure the carriage against rotationon the pipe. and means establishing a driving relation between the motorand toothed carrier wheels.

5. A machine for cleaning the exterior surface of pipe lines including acarriage, a motor thereon, a cleaner connected to the carriage. motoroperated means for rotating the cleaner about the pipe to clean thesame, wheels on which the carriage is mounted, and sup porting themachine on the pipe, means for spraying paint on said pipe behind saidcleaning means, said spraying means including an annular nozzle aroundthe pipe and means for supplying paint and pressure fluid to saidnozzle.

In testimony whereof I have signed my name to this specification.

FRANK KINZBACH.
